Sunset, Waun Mawn stone circle, Pembrokeshire

Waun Mawn (Welsh for "peat moor") is the site of a dismantled Neolithic stone circle in the Preseli Hills of Pembrokeshire. The diameter of the circle is estimated to be 110m (360ft), the third largest diameter for a British stone circle. The site is located just to the north of the broad east-west ridge of the Preseli range. There are four remaining stones, one standing and three prostrate. They are of the same Pembrokeshire bluestone to be found at Stonehenge in the parts believed to have formed the original circle there. During 2017 and 2018, excavations by the UCL team of archaeologist Mike Parker Pearson, revealed that Waun Mawn had originally housed a 110m diameter stone circle of the same size as the ditch at Stonehenge. The circle also contained a hole from one stone which had a distinctive pentagonal shape, very closely matching the one pentagonal stone at Stonehenge (stonehole 91 at Waun Mawn/stone 62 at Stonehenge). Both circles appear to be oriented towards the midsummer solstice. Following soil dating of the sediments within the revealed stone holes, it has been argued by Parker Pearson, that the circle of stones was built c.3400–3200 BC and then between four and five thousand years ago was mostly disassembled, dragged across land and reassembled at Stonehenge in Wiltshire, some 230 km (140 miles) distant. Why and how this was managed remains a mystery. Information taken mostly from Wikipedia
